Venetoclax-Induced Symmetrical Drug-Related Intertriginous and Flexural Exanthema (SDRIFE): Implications for Diagnosis and Treatment Continuation.

Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) is an uncommon type of cutaneous drug eruption, most frequently associated with antibiotics such as amoxicillin. Reports of SDRIFE induced by anticancer agents remain limited. We describe a case of SDRIFE in a 77-year-old man treated with venetoclax for acute myeloid leukemia. The eruption developed shortly after drug initiation and resolved rapidly following drug withdrawal without systemic involvement. Notably, venetoclax was continued for a certain period after onset without progression of symptoms. This case highlights the importance of recognizing SDRIFE in patients receiving chemotherapy and suggests that continuation of the causative agent may be feasible in selected cases.
